4.16 BAROMETRIC PRESSURE METER
The optional Barometric Pressure unit (
SU-1
) brings to the
HX460S
the unique
capability of providing readout of the current barometric pressure. The
SU-1
unit requires calibration of the ‘offset’ parameters, so that the pressure reading
will be correct. To do this you must have a barometer to use as a reference as
you adjust the
SU-1
to match its reading; see section
4.17.6 boF (Barometric
Pressure Offset)
. The
SU-1
Barometric Pressure Unit can be installed in the
transceiver by referring to the following illustration:
SU-1 Operation
1. Set the
SQUELCH CONTROL
knob to the “Squelch Threshold” point.
2. Hold down the
H/L
key for at least 1 second; this initiates measurement
of the current Barometric Pressure.
3. After few seconds, the current Barometric Pressure (in mm of Hg) will
appear on the display.
4. To return to normal operation, again hold down the
H/L
key until the
HX460
shows the last selected working channel; alternatively, turn the
squelch counter-clockwise until noise is heard. The display will revert to
the last channel selected. Return the squelch control to the “threshold”
position to resume normal operation.
Installation of the SU-1
1. Make sure that the transceiver is off. Remove the hard or soft case, if
used. Remove the battery pack.
2. Locate the connector for the
SU-1
under the caution seal in the battery
compartment on the back of the radio, just peel off the caution seal.
3. Align the connector on the
SU-1
with the transceiver’s connector
and gently press the unit into place.
4. Affix the new (supplied with the
SU-1
) caution seal, and replace the
battery. Installation is now complete.
